C.S. Silk, a six-length winner of the Arlington-Washington Lassie (gr. III) as a 2-year-old last September at Arlington Park, returns to the site of her biggest victory July 18 in the $150,000 Arlington Oaks (gr. III).

Winchell Thoroughbreds and Gainesway Thoroughbreds' Hightap ran right by odds-on favorite Luster in upper stretch and sprinted her way to a 3 1/4-length victory in the $111,500 Dogwood (gr. III) for 3-year-old fillies at Churchill Downs May 30.
